Why are my pictures are blurred and have a pinkish hue

I don't know why. But if I had the camera in my hands I would check the settings. If the camera was in Automatic In the menu settings. Also how the White balance was set. It also should be in automatic.
It is great to try to achieve better pictures, by changing the settings, but the best thing to learn is to switch all settings back to automatic, when ready. So the next time you use the camera you won't get surprises.
If the quality of the pictures does not become better after you switched to automatic, you should contact a Nikon certified repair centre close to you.
